What Are the Common Types of Allergies in Kids?

Childhood allergies are a common condition that can affect kids of all ages from any background, causing a range of uncomfortable symptoms. The most common types of allergies children deal with include seasonal allergies, pet allergies, indoor allergies, and food allergies.

Seasonal Allergies

Seasonal allergies or hay fever are typically brought on by outdoor allergens such as tree pollen, grass pollen, or weed pollen. These allergens can trigger allergic reactions, causing symptoms like a runny nose, watery eyes, nasal congestion, and sneezing. The effects are often most noticeable in the spring and fall when pollen counts are highest.

Pet Allergies

Pet allergies are another common type of allergy in children. These are caused by exposure to proteins found in the pet dander, saliva, or urine, particularly in dogs and cats. Allergy symptoms in kids with pet allergies can include a runny nose, itchy or watery eyes, and sometimes allergic asthma or skin reactions such as hives or eczema.

Indoor Allergies

Indoor allergies can occur year-round and are often caused by allergens such as dust mites and mold. Dust mites, which live in items like bedding and upholstered furniture, and molds, which thrive in damp areas, can cause allergic reactions. Symptoms of these allergies in children may include a runny nose, sneezing, and itchy eyes. Regular cleaning and maintenance can help reduce exposure to dust and mold allergies.

Food Allergies

Food allergies are a significant concern, particularly as they can cause serious allergic reactions. Common food allergens include milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish. These can cause allergy symptoms in kids that range from mild, such as a rash or upset stomach, to severe, such as difficulty breathing, or even anaphylaxis, a potentially life-threatening reaction that requires emergency medical attention.

Identifying Allergy Symptoms in Kids

Understanding the symptoms of allergies in kids is crucial to ensure their well-being. Your child’s pediatrician can offer invaluable help in recognizing and diagnosing these common symptoms. Early identification can be pivotal in managing allergies, ensuring your child’s health, school performance, and overall happiness aren’t compromised. Often, the signs of allergies can be categorized as physical, respiratory, gastrointestinal, skin-related, or behavioral.

Physical Symptoms

One of the first telltale signs of allergies in children is often physical discomfort. When a child regularly sneezes or coughs, or frequently breaks out in rashes or hives, it’s important to identify the cause of these symptoms in order to find the most effective treatment.


Children’s respiratory systems are sensitive and can easily indicate the presence of allergies. For instance, allergic rhinitis often manifests as a cycle of sneezing and a constantly blocked or runny nose. If your child frequently has a dry cough or experiences shortness of breath, they might have allergic asthma.


When the digestive system reacts negatively, it can indicate an allergic reaction. Common symptoms of allergies linked to the gastrointestinal tract include frequent abdominal cramps, nausea, and episodes of vomiting or diarrhea.


The skin is another key area where allergy symptoms surface. Watch out for conditions such as allergic contact dermatitis or the sudden appearance of an allergic rash. Hives or swelling on different parts of the body can also point toward a potential allergic reaction.


Not all allergy symptoms are physical. If your child constantly seems tired, under the weather, or unusually foggy-headed, it could be due to allergies. Even temperamental shifts and mood changes can be driven by the discomfort of persistent allergic reactions. Allergies can make it harder to sleep at night which can result in brain fog and fatigue.

Allergy Management Strategies

Managing allergies, especially in children, requires a strategic approach both at home and at school. Implementing these effective strategies can significantly reduce the risk of allergies and help ensure a safer environment for your child.

At Home

  • Hygiene practices: Maintaining a clean home environment can significantly help in managing allergies. Regular dusting, vacuuming, and washing of bedding can help eliminate common allergens such as dust mites. Clean your environment thoroughly, particularly your child’s bedroom to avoid common allergy triggers such as animal dander.
  • Pet management: If your child is allergic to pets, consider keeping pets outdoors or even designating certain areas in the home as pet-free zones. Regular grooming of pets can also reduce allergens.
  • Dietary adjustments: If food allergies are present, modifying your child’s diet is important. This might involve reading food labels carefully and avoiding allergen-containing foods.
  • Use of air purifiers: Air purifiers can help to remove airborne allergens such as pollen or pet dander. This can improve air quality and lessen the chances of allergic reactions.

At School

  • Communication with school staff: It is important to inform teachers and other school staff about your child’s allergies. Provide clear instructions on how to handle any potential allergic reactions.
  • Allergy action plan: Developing an allergy action plan with your pediatric allergist and sharing it with the child's school can be a life-saving step. This plan should include symptoms to look out for and steps to take in case of an allergic reaction.
  • Safe food practices: If your child has a food allergy, coordinate with school meal services to ensure safe food practices. This could include special meal plans or precautions during snack and meal times.
  • Medication accessibility: Ensure your child’s necessary medications, such as antihistamines or epinephrine auto-injectors, are easily accessible at school. School staff should be trained on how to administer these medications if needed.

How Sublingual Immunotherapy Can Help

Sublingual immunotherapy is an innovative method designed to treat childhood allergies and asthma. This treatment involves placing allergy drops or tablets containing small amounts of an allergen under the tongue, helping the body build a tolerance over time. The process is non-invasive, making it a comfortable option for children.

However, parents should note that this option is only for children aged 5 years and older. The main advantage of sublingual immunotherapy is that it addresses the root cause of allergies, not just the symptoms. Instead of simply using allergy medications to temporarily relieve symptoms, this method aims to provide long-term relief by decreasing the body’s sensitivity to allergens.

The next best thing about sublingual immunotherapy is its convenience. Parents can easily administer the treatment at home, without the need for regular office visits, making it a practical option for busy families.

Note that while SLIT can effectively treat pollen allergies, pet allergies, and indoor allergies, it is not a treatment for food allergies. Therefore, if your child has food allergies, consult a pediatric allergist to find a more suitable treatment option for your child.

When to Seek Medical Help for Allergy Symptoms

Knowing when to seek medical help for allergy symptoms in children is crucial for ensuring their well-being and safety. So how do you know when to seek medical care for your child? Here are some signs to watch out for.

  • Persistent symptoms: If allergy symptoms such as sneezing, coughing, skin rashes, or gastrointestinal issues persist for more than a week despite home management strategies, it’s time to seek medical help. Chronic symptoms may suggest a more severe allergic reaction or the presence of an unrecognized allergen.
  • Difficulty breathing: Any form of breathing difficulties, such as wheezing, shortness of breath, or a child feeling tightness in the chest, warrants immediate medical attention. These can be signs of a severe allergic reaction, such as anaphylaxis, which can be life-threatening.
  • Food allergy reactions: Food allergies can cause a range of symptoms, from mild to severe. If your child experiences symptoms like swelling of lips, tongue, or throat, difficulty swallowing, or a sudden drop in blood pressure after eating a certain food, seek immediate medical help.
  • Ineffective medication: If over-the-counter allergy medications are not easing your child’s symptoms or if side effects occur, consult a pediatric allergist. They can recommend a different treatment strategy or prescribe stronger medications if necessary.
  • Interference with daily activities: If allergies are disrupting your child’s daily activities, sleep, school performance, or overall quality of life, it’s recommended to seek professional help. An allergist can provide an accurate diagnosis and develop a comprehensive management plan tailored to your child’s needs.

Early diagnosis and management of allergies can help prevent complications and improve your child’s health and comfort. See your child's pediatrician immediately if you notice any of these signs. Even when you’re in doubt, don’t hesitate to reach out to a healthcare professional.
